Bought one last weekend, didn't work on any Radeon
GPU (9250SE, HD3200 and HD6950) via DVI. Really weird issue as the display would only work with vga-dvi adapter when my old display was connected as second display... When connected alone via DVI, the screen went black (power save) after Windows loading screen. XP, Win7 and Win8 Preview all had the same problem. Without any GPU drivers it was working. And of course when tested in the store with a GeForce
equipped test PC, all worked fine. Returned it and got a full refund.
